Subject: [PATCH v2 15/17] MIPS: JZ4780: DTS: Update DMA node to match driver changes

The driver now accepts two memory resources, the first one for the
channel-specific registers, the second one for the controller-specific
registers.

Note that older devicetrees, without this commit, will still work with
the jz4780-dma driver.
